What is the difference between mupeg and mpeg?

Answer 1

MPEG is a family of international standards to compress audio and video.

I have no clue what Mupeg is. Are you sure you spell it correctly?

If you mean mjpeg, this is Motion JPEG and it is a video based on multiple JPEG frames. MPEG is far more effective in compressing video than MJPEG, which is popular in digital cameras that have already a JPEG encoder for photos.

Answer 2

MPEG-1 defines a group of Audio and Video (AV) coding and compression standards agreed upon by MPEG (Moving Picture Experts Group). MPEG-1 video is used by the Video CD (VCD) format and less commonly by the DVD-Video format. The quality at standard VCD resolution and bitrate is near the quality and performance of a VHS tape. MPEG-1, Audio Layer 3 is the popular audio format known as MP3. As cheaper and more powerful consumer decoding hardware became available, more advanced formats such as MPEG-2 and MPEG-4 were developed. These newer formats are more complex and require more powerful hardware, but the formats also achieve greater coding efficiency, i.e., quality per bitrate.
